Supply of two generator sets for a solar power plant

/in , /by

Another achievement by our distributors.

We’ve supplied two gensets of 220 and 462 kVA, 220-127Vac at 60Hz, prepared to operate under CFE norms according to the degree of seismicity in Mexico as well as the area’s semitropical characteristics.

With a capacity of 170 MW, the Santiago photovoltaic power plant is located in the state of San Luis Potosí (México). It’s a large complex, whose construction began in 2017 with the participation of 1.000 workers. The power plant was built with the idea of supplying enough electricity to power 138.000 homes.  

Its 672.000 solar panels turn the Santiago power plant into one of the largest renewable energy installations in terms of investment (250 million dollars) and also one of the most spectacular, not only in regards to its size (it occupies 750 hectares), but also to the results its expected to achieve: it was built with the objective of preventing the emission of 340.000 tons of CO2 into the atmosphere each year.

The Galician company Genesal Energy participated in this megaproject through the design and supply of two generator sets of 220 and 462 kVA, 220-127 Vac at 60 Hz, prepared to operate in the area’s special conditions, such as the semitropical climate.

Both units were manufactured in Genesal Energy’s headquarters, located in the town of Bergondo, in A Coruña (Spain), with the goal of guaranteeing the correct operation of the booster and switching substations during emergency situations, providing the power necessary for the auxiliary services, emergency lighting, etc.

High precision

Both gensets are high precision units, whose design has been thought out to the very last detail to comply with the client’s requests. They have the following features:

The first unit (GEN220FC) is soundproof type and has a 500 L fuel tank integrated in its baseframe, while the second (GEN462F) has a 1.000 L fuel tank. Both special gensets comply with all technical requirements established by CFE (Comisión Federal de Electricidad or Federal Electricity Commission) norms, the prestigious certification that the CFE awards and which elevates the company to the category of trusted supplier.

The CFE-LAPEM certification is granted by the LAPEM (Laboratory for Equipment and Materials Testing), an organization dependent on the CFE, and Genesal Energy received said distinction last year upon passing the audit process carried out by LAPEM in the company’s headquarters, thus becoming part of the select group of companies which have been awarded this certification, a true symbol of excellence.

Features

  • GEN220FC 500L fuel tank integrated into the base frame, Soundproof type, and with technical features following CFE (Federal Electricity Commission of Mexico) standards, painting with finish according to CFE norms.
  • GEN462F Approved 1000L double-wall fuel tank for external installation, with technical features following CFE (Federal Electricity Commission of Mexico) standards, painting with finish according to CFE norms.

 

Made to measure energy solution for the Almaraz Nuclear Power Plant

/0 Comments/in , /by

Both the reactors at the Almaraz Nucelar Power Plant in Caceres (the oldest in Spain) supply 7% of the nations energy demands.

The plant is located in an area know as Ribera del Rio Tajo, and they have recently placed their trust in GENESAL ENERGY to design an emergency back up generator set capable of dealing with any potential incident.


The project consisted in designing, building, installing and commissioning a genset capable of supplying a 110kVA of power to supply energy to the Individual Temporary Storage (ITS), which alongside the fuel pools, allow for temporary storage of used combustibles from the reactors in the event of a power failure.

Genesal has designed a soundproofed genset inside a 20ft container with an interior control room configured for automatic start up. The bench frame incorporates a 700 litre fully bunded fuel tank, providing the genset with up to 25 hours autonomy. The genset has been specially designed to work at 45°C as well as resist seismic movements, in order to comply with security norms.

To meet with the client’s specific needs the genset was designed with an independent control room and power output with various local controls to manage the genset and other parts of the installation.

Load bank

In the switchgear output of the grid/genset, switches are fitted for each area of the ITS in the power plant. Each one can close or open via pushbuttons or using a pre-programmed sequence designed by the client.

For the correct functionality of the genset, a separate room within the container was built to hold a resistive load bank which is connected to the genset output always and when the load is less than 40% of its maximum capacity. This allows for fuel use optimization and prolongs the lifetime of the genset (normally a genset is recommended to work at 70/80% of its maximum).

The load bank can connect to the genset manually via pushbutton for maintenance work. It is also important to highlight the implementation of signals exchange in the Distributed Control System (DCS) of the power plant, for example the state of switchgear, of the genset and a measurement of zero return to detect grounding failure in the installation.

Emergency Power for Phosphates Treatment Plant in El Jadida, Morocco

/in , /by

The project has been designed for one of the most important companies in the engineering and constructin sector, with headquarters in Marseille (France).

Situated 80KM south of Casablanca and 17Km from El Jadida is the Jorf Lasar industrial complex, a phosphates treatment plant which Genesal Energy has supplied with 3 specially designed gensets for emergency back-up.

The plant whose installations cover an area of 1,700 hectares began its production in 1986 and its numbers are quite impressive: the recuperation of 2 million tonnes annually of P2O5 in the form of phosphorus acid.

Genesal Energy has supplied this elaborate facility in Morocco with a genset island comprising of identical generators for outdoor use (3 units at 400V/50Hz containerised with a control system) designed to work in parallel or if necessary individually. Five circuit breakers make up the switchgear.

In detail

As with every project undertaken by Genesal, the control system designed for this phosphate treatment plant was managed to the tiniest detail:

  • If the gensets are operational, they can be synchronised, either with the output switch of each genset or with the coupling point, therefore reducing the number of movements required by the switches in case of changes in the operational format.
  • If a generator is stopped, the circuit breaker is disabled to avoid damage from unwanted power inputs from external busbars
  • If the client has not indicated that a connection panel should receive an electrical feed, the incoming power cabinet circuit breaker will not be permitted to close (not even manually), in order to avoid short circuits caused by external voltage not from the actual genset island.

We are involved in the extension of the Los Azufres plant in Mexico, which obtains renewable energy from the centre of the earth.

/in , /by

The genset supplied by Genesal Energy is ready to power the critical loads at2,856 M above sea level, where the plant is situated.

Geotherm is a renewable energy source which is generated by the heat expanding from the core of the earth. Currently, Mexico is one of the most advanced countries in this field, and in Los Azufres the country’s second largest reserve also one of the biggest in the world is found (the largest in Mexico being in the state of Baja California).

The Los Azufres power plant is located in the state of Michoacan, 250 KM from the capital Mexico City. Due to the potential of this energy source, the Federal Commission for Electricity has driven the construction of Los Azufres III-Phase 2 expansion, with a net capacity guarantee of 25MW. This will be focused on supplying power to the Michoacan cities of Hidalgo and Zinapecauro. The objective is to ensure a stable and renewable supply for the ever-increasing energy demands in the region.

Genesal Energy has supplied emergency back up power for the plant, a made to measure generator set, very different to standard gensets, in that it can operate at almost 3000M above sea level.

The generator set, was the result of an exhaustive study detailing all the technical requirements of the project. Various aspects were analysed such as the conditions the genset would be working in, as well as calculating the loads it would support and the load steps in order to determine the most adequate engine and alternator.

The role of the new generator set in the Los Azufres Geothermal Plant is to supply power to the critical (essential) loads in the case of a mains grid power failure, with the objective of bringing the power plant to a safe shutdown and not a sudden stop. This is achieved using an Automatic Transfer System (ATS) to switch the power from the mains to the genset.

Some other interesting facts about this Project

  • The control panel was designed to a very specific specification, which was supplied by the client’s engineers – requiring a control cabinet with a PLC (Programmable Logic Controller) and a Siemens Siplus touchscreen.
  • The control panel and the entire genset installation has been prepared to work in an environment with a high concentration of H2S (sulphuric acid – a gas which is heavier than air, inflammable and colourless). To protect against H2S and for easy maintenance all the PLC cards are covered with an acrylic based plastic. Additionally, the connectors on the cards and where they connect are gold plated to withstand a permanent concentration of 3mmm of H2S gas.
  • It comes with a Modbus tcp/ip card and a fibre optic converter via a manageable switch with two fibre optic ports to create a fibre optic ring and guarantee continued communications.
  • As well as communication, the most important signals are sent wired. This ensures all the genset information is stored in the Scada system in the DCS of the geothermal plant, and total control via SCADA.

Power generator for an airport mobile tower – Kenya

/in , /by

Genesal Energy has supplied 2 gensets of 20 kVA prime power to supply electricity to a mobile control tower.

Mounted on a semi-trailer truck with an elevation system of up to 9.5 M above ground level, allowing the controller to have clear visibility. The control tower also comes fully fitted with telecoms systems and can function as a fully operational control tower.

The gensets designed in our manufacturing plan will be used to supply power to this somewhat unusual type of control tower, guaranteeing it has power in the event of a mains grid failure. The gensets have also been prepared and set up to control other aspects of the mobile control tower such as the hydraulic mechanisms of the vehicle that supports the tower.

The principle characteristics of the project design called for redundant diesel generators, both for emergency power; the energy supplied comes from one of the two gensets, with the second genset remaining as back up. Should there be a further power cut associated to the 1st genset, the second genset will then start-up, this also applies if the 1st genset is undergoing maintenance.

Features

  • Redundant sets.
  • Ultra-compact design.
  • Units easily integrated into the client’s existing infrastructure.
  • The soundproof canopy is fully removable to allow mechanical access for maintenance tasks, given the limited space available.
